Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a yarn separator in which a plurality of warp yarns run through a yarn separator and in which a part of the pins of the yarn separator is different from the pins of other parts.

[0002]

[Prior art]

 The applicant proposes, based on the application of Japanese Patent Application No. 4-32833, to divide a plurality of warp yarns into a plurality of pieces in the width direction, divide them into groups, and detect a yarn break for each group. In applying the above technology, when the threading pitch of the warp threads to the separators is made different for division (grouping), when the warp threads are first set on the guide pins, the pin pitch is Therefore, it is not possible to judge which part should change the through pitch. Therefore, the number of pins is counted from the end in the width direction, but the work is complicated and, as a result, a lot of work time is required.

[The purpose of the device]

 The present invention is to make it possible to easily detect warp yarn breakage and detect a yarn breakage position in addition to threading at the position of the yarn separator.

[0004]

[Solution of the device]

 In view of the above object, the present invention provides a warp thread guide device in which a plurality of sheet-shaped warp threads travel through the pins of a thread separator, and a part of the guide pin is visually different from other pins. By doing so, multiple warp threads can be easily specified in the width direction.

【Example】

 FIG. 1 shows a warp guide device 1. The plurality of warp yarns 2 have a sheet shape on a plane, come into contact with the guide roll 3, pass through the yarn separator 4, and pass through the detection area of the yarn breakage sensor 5 such as a light reflection type, a light transmission type, or an image analysis type. Run in the winding direction. In this embodiment, the yarn breakage is detected by the two yarn breakage sensors 5. Each of the yarn breakage sensors 5 uses a half of the sheet width of the warp yarn 2 as a detection area, and is movable along two guide rails 6 parallel to each other in a direction orthogonal to the warp yarn 2 and is fed. By the screw 7 and the feed motor 8, the sheet-like warp yarn 2 can be moved at a predetermined speed in the width direction.

In this way, the yarn separator 4 is provided on the upstream side of the yarn breakage sensor 5, and the guide roll 3 is provided in the vicinity of the yarn breakage sensor 5, that is, on the upstream side as one of the upstream side and the downstream side. Has been. With this arrangement, the vertical swing of the warp thread 2 is suppressed, and the warp thread 2 is stored in the area where the thread breakage sensor 5 can detect.

The yarn separator 4 is composed of a separator body 40 extending in the width direction of the warp yarn 2, and a plurality of guide pins 41, 42 provided in a comb shape in a state of being orthogonal to and parallel to the separator body 40. It is composed by. The pitch of the pins 41 and 42 is determined by the number of yarns and the sheet width, but it should be an appropriate size so that the yarn does not shake due to the thickness that is the minimum air space of the yarn type used. Is set to.

Then, the pin 42 is configured to be visually different from the other pins 41. That is, the pin 42 has a height different from that of the other pins 41 by lowering it as shown in FIG. 2 or vice versa, or making it thicker as shown in FIG. Or by conversely making it thinner than others, or visually as shown in FIG. 4 by the color difference of different materials, or by the coloring of all or part thereof. It is configured differently from the other pins 41.

Usually, the position of the part of the pins 42 is used for specifying the detection area of the yarn breakage sensor 5, or for dividing a large number of warp yarns 2 and for dividing a large number of types of the warp yarns 2. The position is set for each application with the aim of making it easier to find the position of the thread breakage.

As another means of visually differentiating, the pins 42 may have a different coarse or fine pitch than the other, as shown in FIG. 5, or as shown in FIG. A projection 43 is provided in correspondence with the projection 43, and the projection 43 has a different shape. As shown in FIGS. By covering one pin 42 with a bridge-shaped cap 45, the pin 42 can be distinguished from the other pins 41. It should be noted that the caps 44, 45 themselves may be colored or may have projections or the like to have different structures so that they can be easily visually identified.

In order to divide the pitch of the plurality of warp threads 2 in the width direction, when the threading pitch of the warp threads 2 is made different by the thread separator 4, for example, if the thread is not passed through the pin 42 having a low height, , The plurality of warp threads 2 can be set in a predetermined number of groups (grouping), and the positions of these pins 42 can be easily specified in the width direction of the sheet-like warp threads 2, so that the warp threads 2 with different pitches can be set. The position of can be easily identified.

Further, when the two yarn breakage sensors 5 are moved over the widthwise half of the sheet-like warp yarn 2 to count the number of the warp yarns 2, the detection area of the sheet-like warp yarns 2 is divided into halves. At this time, at the central portion in the sheet width direction, a pin different from the other pins 41, for example, by providing a pin 42 of a different color, the boundary of the detection area of each thread break sensor 5 can be simplified due to the existence of the pin 42. Can be identified. For this identification, a dedicated sensor 9 for detecting the pin 42 is incorporated near the thread break sensor 5 as shown in FIG. 1, and the presence of the pin 42 is detected by the photoelectric sensor 9. To be done.

Further, when the plurality of warp threads 2 and the plurality of thread types are set in a divided state, by covering the pin 41 at the boundary position to be divided with the cap 44 or the cap 45, the division for each thread type is performed. Can be set easily, and confirmation after setting is also easy.

Further, as illustrated in FIGS. 9 and 10, the pin 42 is bent into an L-shape so that it is visually different from the pin 41 of the other part, and the tip part of this pin 42 is a transparent type. It may be detected by the sensor 9. Instead of bending the pin 42 itself, a cap 46 with a protrusion 47 may be fitted as shown in FIG. In this case, the protrusion 47 can be detected by the transmissive sensor 9. In any of the embodiments, since the transmissive sensor 9 can be adopted, the boundary of the detection area of the yarn breakage sensor 5 can be reliably detected.

When the yarn breakage sensor 5 detects the number of the warp yarns 2 cut from the reference position, for example, one of the weaving ends or the central weaving end position by counting the number of yarns, the worker By counting the positions of the pins 42, the thread breakage position can be easily specified from the reference position. For this reason, the pin 42 is provided, for example, for every tenth pin 41 or for every predetermined distance.

Although two pins 42 are provided in the above embodiment, one pin or three or more pins 42 may be provided instead.

[Effect of device]

 In the present invention, some of a large number of pins of the thread separator are configured differently from the other pins, which facilitates the operation when the warp thread is divided in the width direction during threading. When confirming the yarn breakage position based on the signal from the breakage detector, the yarn breakage position can be easily specified.
